Embodiment Construction

[0039] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the second fitting formula of the frequency-up speed of the compressor in the specific implementation is v y = kT in +b is shown as an example, but the form of this fitting formula is not static, and those skilled in the art can adjust it according to needs, so as to adapt to specific applications. For example, the second fitting formula can also be v y = kT in 2+b etc.

[0040] First of all, it needs to be explained that generally air conditioners include indoor units and outdoor units. The indoor units are equipped with indoor heat exchangers and indoor fans. Wait. The indoor unit is usually provided with a control...

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner in a refrigeration mode. By adoption of the control method of the air conditioner in the refrigeration mode, the problems of poor universality and poor user experience of an existing control method of an air conditioner are solved. The control method of the air conditioner in the refrigeration mode comprises the steps that the indoor environment temperature is obtained; the acceleration of an outdoor fan is calculated according to a first fitting formula; the frequency increase speed of a compressor in the frequency increase stage is calculated according to a second fitting formula; the speed is the outdoor fan is controlled to be increased to a target rotating speed atthe acceleration; and during, before or after the speed of the outdoor fan is increased to the target rotating speed at the acceleration, the frequency of the compressor is controlled to be increasedat the frequency increase speed. By adoption of the control method of the air conditioner in the refrigeration mode, the universality of the air conditioner can be improved, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method in cooling mode. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and this requirement is particularly evident in household appliances. Taking the air conditioner as an example, in order to meet the needs of users for rapid cooling and bring users a comfortable experience, the existing air conditioners generally make the compressor quickly increase in frequency to run at a higher frequency (such as frequency up to the maximum operating frequency). In the process of the compressor rapidly rising to high frequency, in order to ensure normal oil return, the compressor is usually forced to continue running at a certain or certain fixed frequency (oil return frequency) for a period of time, and continue to increase the frequency after the oil return is...
